Pope Leo XIV diagnosed with lung cancer after surgery

Pope Leo XIV has been diagnosed with lung adenocarcinoma after surgeons removed the lower lobe of his right lung, the Vatican said Tuesday.

The 71-year-old pontiff underwent a video-assisted procedure at Rome’s Gemelli Hospital after doctors discovered a small nodule during a recent health check. Tissue examined during the operation confirmed pulmonary adenocarcinoma, which had been suspected in preoperative tests.

The Vatican said the operation itself lasted about 90 minutes and was successful, with no complications. Leo regained consciousness normally and returned to his hospital room. Doctors removed the entire lower lobe to achieve what the Vatican described as a “radical” resection intended to eliminate the suspect tissue.

The cancer’s stage and whether it has spread have not been disclosed. Further tests are being conducted, and the Vatican has not announced whether the pope will need chemotherapy or another treatment.

Leo is expected to remain in the hospital for about a week, and his public audiences have been canceled through October 20. It remains unclear whether his recovery will affect a Latin America trip scheduled to begin November 6.

The surgery was Leo’s first hospitalization since he became head of the Catholic Church in May 2025. Before entering the hospital, he waved to well-wishers gathered outside.

WHAT THE EDITOR DID

The second model checked the writer's draft against the same sources and changed it before publication. Struck words were in the draft; underlined words are its corrections.

WHAT IT FLAGGED editor revise: No material problems require correction. - "The 71-year-old pontiff underwent a video-assisted procedure at Rome’s Gemelli Hospital after doctors discovered a small nodule during a recent health check.": Sources say the nodule was discovered during a recent routine health check or medical checks, not specifically that the procedure occurred after the discovery during that check; acceptable? Material issue is 'after' sequence supported. no issue? Need every material only. Maybe title says diagnosed after surgery yes. - "Leo is expected to remain in the hospital for about a week, and his public audiences have been canceled through October 20.": The sources say the Vatican expected recovery to take about a week or that he was expected to remain in hospital for about a week; this is supported. No material problem. - "It remains unclear whether his recovery will affect a Latin America trip scheduled to begin November 6.": Sources conflict between South America/Latin America but Al Jazeera supports Latin America tour begin Nov 6. No problem.
